...Show More Authors

Background: Nicotine is the foremost chemical constituent responsible for addiction in tobacco products, in the non-ionized condition can be easily absorbed via epithelial tissue of the lung, the mouth, the nose  and across the skin

Objective:The study examines the harmful effect of   the nicotine which is an important component of cigarette in vitro.

Type of the study: Cross-sectional study.

Methods: Examines the harmful effect of   the nicotine which is an important component of cigarette in vitro by using two types of lung cancer cell lines (H460 TP53+/+, H441 TP53-/-).

Results: The results showed the total count of H460( TP53+/+) cancer lung cell lines  was (5.2 ×106 cells /ml) , the number  (4.9 ×106 cells /ml)  of them were alive  and (3.6×105 cells /ml) of them  were dead, with percentage  of viability (93.15%), while the total count  of H441( TP53-/-) lung cancer cells was (5.1 ×106 cells /ml), the number (4.1 ×106 cells /ml)  of them were alive, and the number (9.9×105 cells /ml) of them   were dead  with percentage  of viability (80.55%). And it  revealed that the nicotine inhibited viability of H460 lung cancer cell lines in all concentrations (1, 10, 500 and 1000 μ M) and the cells were completely abolished by treatment with (1000 μ M) when the viability reached to minimum percentage (3.43%), while nicotine induced proliferation in H441 lung cancer cell lines even in lowest concentration (1 μ M), whereas the viability reached to maximum percentage (41.04%) at concentration (1000 μ M). Also it noticed that  the treatment with nicotine at concentrations (1,10, 500 and 1000 μ M ) for 24 and 48 hr  induced the apoptosis but not necrosis in H460 lung cancer cell lines, especially at the highest concentrations (1000 μ M) for 48hr when the percentage of apoptosis reached to the maximum value (55.5%), however  it was induced proliferation in H441 lung cancer cell lines with highest proliferation at concentration (1000 μ M), when the percentage apoptosis value reached to the minimum percentage (1.5%) when compared to un treated  cells (control).

Conclusions: the cells lack to TP53(H441 TP53-/-)  will proliferate when exposed to nicotine and some of these cells will suffer from necrosis as a replacement of apoptosis.

Analysis of the Effects of Aggressive Shot Peening on Fatigue Life of 7075 – T6 Aluminum Alloy
...Show More Authors

 For many years controlled shot peening was considered as a surface treatment. It is now clear that the performance of control shot peening in terms of fatigue depends on the balance between its beneficial (compressive residual stress and work hardening) and beneficial effects (surface hardening).

The overall aim of this paper is to study the effects of aggressive shot peening on fatigue life of 7075 – T6 aluminum alloy. The fatigue life reduction factor (LRF) due to the aggressive shot peening was established and empirical relations were proposed to describe the behavior of LRF, roughness and fatigue life. The benefits of shot peering in terms of fatigue life are dependent on the shot peening time (SPT).
